Shrink safety line

"There are still 42 hours, we must hold on!"

"Attention all combat units, throw all the throwing objects in your hands into the zombie group!"

"Fighter team, immediately deploy the strongest firepower!"

"Soldiers on the first battlefield, fight and retreat, speed up and shrink the standing circle!"

Li Chen immediately ordered,

"receive!"

On the radio, there were responses from various battle groups.

At this point, it doesn't matter how much ammunition is consumed.

Throwing bombs recklessly is the kingly way!

With fighter groups no longer saving ammunition.

boom—

The first battlefield suddenly became a hellish scene!

30 junior fighter jets hovered in the sky.

Keep dropping shells.

Every time it can hit the place with the most zombies.

In an instant, the pressure on the android fighters on land was reduced!

"Okay! I can finally feel proud!"

"Attention, Team 5, attention, Team 5, a large number of zombies are rushing towards you! Request air support!"

"Team 6 calls for air support! Repeat! Squad 6 calls for air support!"

Humanoid warriors on land.

Keep sending messages over the radio.

One of the reasons why these second-order zombies are difficult to deal with is that they have developed some IQs.

When the firepower of a certain line of defense is relatively weak.

There will always be some low growls in the zombie tide.

It means that these zombies are communicating!

After a while, the defense line with relatively weak firepower will usher in several times the zombies!

Fortunately, fighter jets started bombing regardless of the cost.

Under raging firepower.

Even pushed the safety line forward 600 meters!

This exciting scene was relayed to the forum through drones.

Get everyone excited!

But for Li Chen, this is just the beginning.

After all, fighter jets don't have much ammunition reserves.

It was originally expected to be able to bomb 1092 times.

After a crazy attack at this time.

The remaining ammunition can only be bombed 190 times.

What a concept.

That is, 30 fighter jets, with 6 round trips, can consume all the ammunition.

And at this time, it was only 6 hours before the zombie tide started!

As the fighter jet ammunition tilted to empty.

The fighter jets began to return gradually.

After all, without ammunition, staying on the battlefield is useless.

The pilots of those fighter jets got off the plane.

Immediately joined other combat groups for the first time to fight!

The first battlefield and fight and retreat.

According to Li Chen's instructions, the safety line was continuously shrunk.

At this time, the safety line is only one kilometer away from the star shelter!

Only 12 hours had passed since the zombie tide started.

This is the time that was delayed only when fighter jets were bombing with all their strength.

This place is less than one kilometer away from the star shelter.

The android warriors are still fighting **** battles.

This is the task Li Chen gave them.

The first battlefield is required to stick to the last half an hour, and cooperate with the members of the resident combat team to complete the equipment!

"Attention the resident combat team, load the gunpowder immediately! Charge the power grid!"

Li Chen is sitting in the helicopter.

Looking at the battle situation on land, start ordering!

At this time, the robot battle group is in the front.

Therefore, there are not many zombies that can reach the star shelter.

The resident combat group dispatched a large number of manpower to arrange fortifications.

This is also plan B that Li Chen has set up long ago.

Before the zombie wave broke out, the power plant in the star shelter was running at full capacity.

A small portion powers the shelter.

Most of them are stored away!

Not to mention there are solar energy and other equipment on the ground, which store all the absorbed energy.

So much so that the star shelter has a lot of power!

High voltage electricity is one of them.

The second is the gully dug by the resident combat group before.

There are bombs buried inside!

These were all hoarded by Li Chen before the doomsday.

It's a pity that compared to the bombs produced by the star shelter's ammunition defense line, these pre-apocalyptic bombs are not powerful enough.

So it has never been used.

It's just that a small part is exchanged for other shelters.

And now.

These bombs can play a vital role!

Buried in a ravine two people high.

When the zombies attack, they will step on the air first and fall in.

Immediately afterwards, the explosives were triggered.

Although it will not directly take the lives of zombies, it can provide time for members of the resident combat team.

Raise the flamethrower and shoot the ravine!

At that time, a large number of zombie waves will be difficult to move!

Because I am afraid that the corpses of zombies will fill up the gully.

Within 1 kilometer of the star shelter, a total of hundreds of them were dug up!

That's why Li Chen asked the android fighters to hold back the tide of zombies as much as possible on the first battlefield.

So that the resident combat team has time to make final preparations!

"Hurry up! There are still a few ravines that haven't filled enough bombs! Team 8, come with me!"

"The flamethrower is fully charged!"

"Move fast! The first battlefield will soon be overwhelmed!"

In the wireless headset of the resident combat group.

Xu Ruoxi's voice kept coming.

All the ravines are filled with bombs!

There are currently 60,000 flamethrowers owned by the Star Refuge.

It is completely possible to have two humanoid fighters and resident combat teams!

But there is the problem.

It takes time to recharge the flamethrower.

It takes 5 minutes at least.

After the tide of zombies comes, a group of fighters must be separated.

Constantly transport back and forth between ravines and charging points.

To ensure sufficient flamethrowers at the forefront!

"The 8th group of the resident combat group is ordered, and you are responsible for transporting the flamethrowers back and forth in 50 ravines!"

"The 9th group of the resident combat group is ordered, and you are responsible for transporting the flamethrowers back and forth in the last 50 ravines!"

"The 10th group of the resident combat group obeys the order, you stay at the charging point and charge the flamethrower as quickly as possible!"

Xu Ruoxi arranged the manpower methodically.

Just then.

"Report to the commander, the security line of the first battlefield has been shrunk! There are still 3 minutes to prepare, and the wave of zombies will reach the first ravine!"

The voice of management comes from the wireless headset.

Originally, Li Chen decided to resist here for half an hour.

The robot warrior has overfulfilled the task and resisted for 40 minutes!

With the sound of the wireless headset came.

Li Chen immediately said: "Resident combat team, rush to the first gully immediately!"

In Li Chen's plan, a gully must persist for at least half an hour.

So time is running out!

Countless soldiers rushed to the first gully immediately.

Hold the flamethrower and stand by at any time!

boom-

All I saw was that the armored vehicle was constantly retreating, firing shells while retreating.

In addition to the armored car driver, as well as the gunner.

The rest of the android fighters quickly formed a team.

Stand behind the flamethrower and hold the railgun!

"Ho **** ho ho!"

"Ho **** ho—"

Follow everyone to their positions.

The second-order zombie wave finally had a face-to-face meeting with the members of the resident combat team!
